TYPE-FINISHING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 596,489, dated January 4, 1898.

Application filed March 18, 1897. Serial No. 628,117. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE S. EAToN,.a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Type-Finishin g Machinery, of which the following is a specification. r

The present invention is a modification of and an improvement upon the devices represented in my application, Serial No. 568,551, filed November 11, 1895, and the same relates to the manner of constructing and adjusting the grooving-tool that grooves the bottom end of the types and also to ledges or supports at the bottom sides of the equalizers upon which the lower ends of the types rest, there being a channel between these ledges within which may pass the gate or projection sometimes left upon the bottom end of the type when the gate or sprue has been broken on? from the type in order that this projection may be entirely removed by the grooving-tool, and I provide a finger actuated by a spring to press upon the upper end of the type to force it downward, so that the bottom end rests upon said ledges during the grooving operation and during the final finishing operation of dressing the bases of the letters at the top and bottom thereof.

In the drawings, Figure 1 is a plan view of part of the equalizers and cutters at the intersection of the channels. Fig. 2 is a Vertical section at the line 2. Fig. 3 is a section of the bed and equalizers and an elevation,

partially in section, of the grooving-tool and the devices for adjusting and holding the same. Fig. 4 is a plan view of the groovingtool and the stock carrying the 'same,'and Fig. 5 is a side elevation of the grooving-tool.

The bed O is at an. inclination usually of about forty-five degrees, and the stationary equalizer E and the adjustable equalizer F are supported by this bed, with the channel between such equalizers, horizontally, or nearly so, and at the end of the stationary equalizer E is a second movable equalizer H, so that the second channel at right angles to the first is between the end of the stationary equalizer E and the side of the movable equalizer H, and a screw is made use of for adjusting the movable equalizers, as in the said application,and the reciprocating pusher I is employed for carrying one type at a time bodily along between the equalizers E and F, during which operation the cutters act to rub or remove the burs or projections at the bases of the letters at the right and left hand sides thereof (such cutters, however, are not shown in the drawings) and the type is carried by .the pusher I into the channel between the equalizers E and H, the advancing side of the type being brought up against the face of the equalizer H, and the second pusher h is employed for moving the types along in the channel between the equalizers E and H, and the movement given to this pusher h is only sufficient to carry one type at a time directly in between such equalizers E and H, and thereby the types are set up in line and pressed downward in such channel.

Below the pusherl is a table or support I, the upper surface of which coincides, or nearly so, with the under surfaces of the equalizers, and hence itcan be moved backward and forward directly beneath the adjacent edges of the equalizers E and F, and it can also pass some distance under the equalizer H,as shown in Fig. 2, and the types as they are fed into the machine pass down between such equalizers E and F, and the lower end of each type rests upon such table 1, during the time that the type is carried along and rubbed as aforesaid, and its advancing edge comes against the face of the equalizer H, and the pusher 71. carries the type off from the table I in between the equalizers E and H before the table 1 and pusher I draw back for taking another type.

The types as they are cast have each a gate or sprue upon the lower end which usually tapers to quite a small connection with the bottom of the type, and these gates are broken off before the types are fed into this finish ing-machine, but sometimes small portions of the gates are left upon the types, which, projecting downward, prevent the bottom ends of the types resting upon the table I, and hence such types are too'high for the grooving-tool to properly act upon the lower ends of such types. I therefore provide ledges consisting of plates 0 c, screwed upon the under surfaces of the equalizers E and H, with their edges projecting slightly to form the ledges upon which the bottom ends of the types may rest, any remaining portions of the gates upon such types projecting down between such plates; and in order to press the types down so that their bottom ends may rest squarely upon these ledges I make use of the finger d, which projects out as an arm over the types as they pass in between the equalizers E and H, and this finger is advantageously covered upon its lower surface with a piece of leather or similar material 10, so as not to injure the faces of the types, and there is a stem (1 extending down from'the finger at through a hole in the equalizer H, and the lower end is rounded and the end of the table I is beveled, so that as the table I completes its movement the finger d is lifted and held until the type has been carried off by the pusher h in between the equalizers E and H, and as the table 1 draws back with the pusher I the fingerd is forced downward by a spring (1 acting between the stem of the finger and a stationary bracket 61 so that the power of the spring is exerted to press the type downward, so that the bottom ends of the types will rest upon the ledges c c and be in a uniform position for their bottom ends to be grooved to the same extent whether any portions of the gates are left upon the types or whether they are not.

In consequence of the finger cl being raised as each type is supplied and a line of types moved along there is no rubbing action of the finger upon the faces of the letters.

The grooving-tool L is preferably a plate of steel of the shape shown in Fig. 5, and it is sufficiently thin to pass up between the ledges c c, and its point nicks or grooves the bottom end of each type in succession as the line of types is forced along between the equalizers E and II. This grooving-tool L passes through and fits closely a mortise in the stock L, which stock is held by screws to the under surface of the bed 0, the screws passing through slots so that the stock can be adjusted; and with this object in view Iprefer to employ a flange f at the end of the stock L, through which passes an adjustingscrew f and by which the stock L and grooving-tool L can be adjusted so that the grooving-tool is central to the channel between the equalizers E and H, and any suitable clamping device may be employed for holding the stock L and grooving-tool rigid after the same have been adjusted.

I have represented a leverg and an eccentric or cam at the end for clamping the stock L to the bed 0. It is advantageous to insert the grooving-tool L from below up through the mortise in the stock L, so that such grooving-tool may be taken out whenever necessary for sharpening or for the insertion of another tool, and the clamp-screwr is made use of for holding the grooving-tool in the stock, and I find it advantageous to make this clamp-screw tubular and pass through the same the conical-ended screw 7", the point of which passes into a hole in the groovingtool L, so as to support such grooving-tool against any downward pressure while grooving the bottom ends of the types, and by this screw 7" the grooving-tool can be raised or lowered, and it is advantageous to employ a spring r to press the grooving-tool down against the adj usting-screw r.

The upper end of the grooving-tool should stand central in the channel between the equalizers E and H, and to aid in setting the machine to different sizes of types it is important to have an indicator -to aid the attendant in adjusting the groover when the machine is changed from one size of type to another; and with this object in View a fine pointer s is extended upward from the stock L adjacent to an indicator-disk t, upon the under side of which is a ratchet-wheel with equidistant teeth that are engaged by a pawl i, and this indicator-disk can be turned around to any desired place, and it has upon its upper surface marks indicating the width of the body as usually designated by the number of points, and the marks are to be so placed that when a given number of point type is to be dressed the disk is turned around with that particular number of points adjacent to the pointer s, and when the said pointer is adjusted by turning the screw f to coincide with the mark upon the disk the grooving-tool will be in position for use and equidistant between the facesof the equalizers E and H. The other portions of the machine corresponding generally to those in the aforesaid application do not require further description herein.

I claim as my invention 1. The combination in a type-dressing machine of two equalizers having a channel between them and a pusher for setting the type up in line and formoving them along progressively in the channel, ledges for supporting the lower ends of the type-bodies, ayielding finger over the entrance end of the channel, means for lifting such finger and holding the same up out of the way while the types are being moved and for allowing the finger to press on the types while stationary to cause their lower ends to rest on the ledges, substantially as set forth.

2. The combination in a type-dressing machine of two equalizers having a channel between them and a pusher for setting the type up in line and for moving them along progressively in the channel, ledges for supporting the lower ends of the type-bodies, a yielding finger over the entrance end of the channel, means for lifting such finger and holding the same up out of the way while the types are being moved and for allowing the finger to press on the types while stationary to cause IIO their lower ends to rest on the ledges and a tool below the channel for grooving the lower ends of the types, substantially as specified.

3. The combination in a machine for finishing types, of equalizers between which the types are moved, a finger extending over the type-channel, a stem upon the same, pushers for moving the types along, a table adapted to receive the bottom ends of the types, such table having an inclined portion to raise the finger, a spring for forcing the finger down, and ledges upon which the bases of the types are received, substantially as set forth.

4. The combination With the grooving-tool, of a stock having a mortise through'it for receiving the groovingtool, a tubular clamping-screw and an adjusting-screw passing through the clamping-screw and having a ta- GEO. S. EATON.
